vWILLIAM H. RAGEY, OF NEV YORK, N. Y.

BURNER FOR- VAPOR-LAMPS.

Specification of Letters Patent No. 25,525, dated September 20, 1859.

To `all whom it may concern:

Beit known that I, VILLIAM H. RACEY, of the city, county, yand State of New York, have invented a new and Improved Lamp; and I do hereby declare that the following isa full, clear, and exact description of the same, reference being had to the annexed drawings, making-a part of this specification, in whioh- Figures l and Y2, are vertical cent-ral sectionsof my invention, the two planes of section crossing each other at right angles.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to an improvement in a lamp for burning without a chimney these hydro-carbons that contain an excess of carbon, and for which Letters Patent were granted to me bearing date June 29th, 1858.

The object of the within described invention is to `obtain a lamp far more portable than the patented lamp above referred to and still one that will operate or burn the material aforesaidmore perfectly and with a more persistent flame.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents a cap which is screwed into the upper end of the lamp and B, is a wick tube which is of the usual rectangular form, passes through the center of the cap and extends a requisite distance above the cap A. The wick tube B, is encompassed by a tube C, which is of slightly conical form and extends a short distance above the upper end of the wick tube. The lower end of the tube C, has a curved flanch a, attached to or formed on it. This flanch is curved upward all around the base of the tube and it is perforated as shown at b. The cap A, is also provided with a similar flanch o, which is bent or curved upward, the two flanches being connected at their outer edges entirely around or at certain points cl', and forming the attachment between the tube C, and the cap A, and also forming an annular chamber d, all around the base of the tube, the perforations o, with spaces o, between the points CZ', forming the only oommunication between the lower end of tube C, and the external air.

On the upper end of the tube C, a cap D, is fitted. This cap is of the usual domeshape and has a slot e, made in its upper end, said slot extending from one side of the cap to the other as shown in Fig. l. Within the cap D, a smallerl capE, is secured, the upper part of which approximates in form to the upper part of the cap D, and it is also provided with a slot f. The upper part of the cap E, however is slotted laterally at opposite sides of its slot f, as shown at g, g, Fig. 2, said slots extending nearly if not quite the whole width of the cap. The lower part of the cap E, is of inverted conical form, as shown clearly in both figuresand it is attachedto the cap D, by hori- Zontal plates it, it, said plates being secured to a cylinder f', which is fitted within a cylinder g', to which the upper part of the cap E, is attached by plates L, the plates z, L, being in the same plane with slot e, below each end of it.

Within the lower inverted conical portion of the cap E, a burner F, is placed. This burnger is of oval form and is equal in length to the diameter of the lower lpart of the cap E, and fits snugly within it. The upper edges z', of the burner are of rounded form as shown clearly in Fig. l, and its lower edge is flush with the lower edge of cap E. The lower edges of the cap E, and

` the burner F, are a trifle above the lupper end of the wick tube B, a space j, being allowed between, as shown clearly in both figures.

Gr, G, represent two curved or arched rods which extend entirely over the slot f, of the smaller cap E, and at a point between the slot f, and the slot o, of cap D. The ends of these rods are attached to the plates L, of the upper part of the cap E. The rods Gr, Gr, as well as the burner F, are constructed of copper.

I prefer to have the burner F, for reasons hereinafter stated, perforated. This burner it will be seen by referring to Fig. l, has its upper part wider than its lower part, or, it may be described as expanding gradually in a longitudinal direction from its lower to its upper end, and transversely it would be preferable to have it gradually contracted from its lower to its upper end, as shown in Fig. 2.

The operation is as follows The wick H, is lighted at the upper end of tube B, and a gas-generating flame ax, produced in consequence of an imperfect supply of oxygen, it being understood that the flame is encompassed by the burner F, which excludes the requisite supply of oxygen suflicient being admitted at the space y', to support an imperfect combustion. In consequence of this imperfect combustion hydrocarbon gas is eliminated and passes up through the burner F, and is allowed to gradually expand, said gas passing through the slots e, of the caps E, D and burning With an illuminating flame bx, at the slot e, of the cap D. The copper rods G, G, perform tvvo functions, they, in common With the burner F, have a tendency to spread or expand the flame thereby presenting a greater surface of flame to the air, and they also divide the mass of heated air into parts so that the same will be brought in Contact With the flame in a more heated and in dierent positions producing at the same time a permanent rarefication and consequent draft in tube C, so that the flame, Will receive .a greater amount of oxygen, and the rods also serve to keep the air in a rarelied state. The burner F, also serves to rarefy the air Within the caps and the tWo caps D, E, cause the air to impinge against the hydro-carbon gas and flame at different points. The slots g, g, in the smaller cap E, also cause a current of air to impinge against and become incorporated With the gas below the top of cap E. The employment or use of the caps D, E, in connection With the burner F and rods Gr, G, enable me to obtain a perfect illuminating flame bx With a comparatively short tube C, for by the use of the caps, burner and rods a good and suflicient draft is obtained through the tube and made to impinge in the most advantageous manner against the flame.

In order to use t-he lamp the Wick H, is lighted and a gas generating flame ax, ob-

tained, the oxygen being admitted to it in small quantities in consequence of the close proximity of the burner F The flame ax, eliminates a hydro-carbon gas Which escapes up through the burner F, slots f, e, and. burns with an illuminating flame bx, at e. When the gas is produced the Wick H, is gently raised until the gas is ignited at e, the flame ax, producing such result in consequence of the perforations in the burner F, which aerifies the gas and permits the flame ax, to ignite it. Were the burner F, not perforated, an auxiliary flame or light would be required lto ignite the gas at the s lot e, and the aerifying of the gas also increases the power and rarefied development of the illuminating llame; Hence the advantage of having the burner F, perforated.

I do not claim a plurality of caps D, E, to deflect the air and cause it to impinge against the flame. Neither do I claim the curved llanches a, c, at the bottom of the tube C, and on the cap A. Nor do I claim separately and irrespective of arrangement a heatconducting rod or Wire G; but

Having thus described my invention what I do claim as new and desire to secure by Letters Patent, is,

The burner F, and curved rods G, G, one or more, in combination With one or more deflecting caps D, E, and draft tube C, arranged for joint o-peration substantially as and for the purpose set forth.
